Answer:

$3.80,26.60, and 41.80 are the right answers

Step-by-step explanation:

All you have to do is divide 58.9 by 15.5 and then the unit rate is 3.80.

So to figure out all the right answers multiply 3.80 by the number of gallon of gas.

This question is based on  concept of simple division. hence the correct option is  (1),(3),(5).

Given:

Cost of  [tex]\bold{15\dfrac{1}{2}}[/tex]   gallons of  gas is = $58.90

So, cost for each gallon of gas is,

[tex]\dfrac{58.90}{15\frac{1}{2} } = \bold{\$3.8}[/tex]

Now, check which of the rates equal to $3.8,

Firstly, divide 41.8 by 11 we get,

[tex]\dfrac{41.8}{11} = \$3.8[/tex]                                                                             ...(1)

                                                 

Now, divide 28.8 by 8 we get,

[tex]\dfrac{28.8}{8} = \$3.6[/tex]                                                                             ...(2)

Now, divide 26.6 by 7 we get,

[tex]\dfrac{26.6}{7} = \$3.8[/tex]                                                                             ...(3)

At last, divide 8.55 by 2 we get,

[tex]\dfrac{8.55}{2} = \$4.275[/tex]                                                                          ...(4)

And, divide 3.8 by 1 we get,

[tex]\dfrac{3.8}{1} = \$3.8[/tex]                                                                                ...(5)

Therefore, the correct option is (1),(3),(5).
